Damien George 05005f679e py: Remove mp_obj_str_builder and use vstr instead.
With this patch str/bytes construction is streamlined.  Always use a
vstr to build a str/bytes object.  If the size is known beforehand then
use vstr_init_len to allocate only required memory.  Otherwise use
vstr_init and the vstr will grow as needed.  Then use
mp_obj_new_str_from_vstr to create a str/bytes object using the vstr
memory.

Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes
on unix x64.

Damien George b66a31c42c stmhal: Allow SPI.init to specify prescaler directly; improve SPI docs. 2014-12-08 21:34:07 +00:00
Damien George 9de6773237 stmhal: Make SPI bus use DMA for transfers.
Uses DMA if interrupts are enabled, polling if they are disabled.

Damien George 480a7ce58f stmhal: Change SPI phase spec to 0,1 to match standard conventions.
Was 1 or 2, now 0 or 1 (respectively).  0 means sample MISO on first
edge, 1 means sample on second edge.

Addresses issue #936.

Addresses issue #921.

Damien George bfa7b480a7 stmhal: For spi_init, add argument to select if NSS pin is enabled.
Most of the time you don't use the NSS pin of the SPI bus, and so it
shouldn't be enabled by default (this gave some bugs in the past).

Damien George b766e79510 stmhal: Initial implementation of cc3k module and driver.
Pulled in and modified work done by mux/iabdalkader on cc3k driver, from
iabdalkader-cc3k-update branch.  That branch was terribly messy and had
too many conflicts to merge neatly.

Damien George ecc88e949c Change some parts of the core API to use mp_uint_t instead of uint/int.
Addressing issue #50, still some way to go yet.

Damien George 40f3c02682 Rename machine_(u)int_t to mp_(u)int_t.

Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Paul Sokolovsky 9b71b16a94 unix,stmhal: Make "mpconfig.h" be first included, as other headers depend on it. 2014-05-02 18:08:16 +03:00
Damien George 8d09640b22 stmhal: Add documentation in comments, and script to generate HTML.
Decided to write own script to pull documentation from comments in C code.
Style for writing auto generated documentation is: start line with ///
and then use standard markdown to write the comment.  Keywords
recognised by the scraper begin with backslash.  See code for examples.

Running: python gendoc.py modpyb.c accel.c adc.c dac.c extint.c i2c.c
led.c pin.c rng.c servo.c spi.c uart.c usrsw.c, will generate a HTML
structure in gendoc-out/.

gendoc.py is crude but functional.  Needed something quick, and this was
it.

Damien George 34f01c2ca1 stmhal: Add some documentation to I2C, SPI and USART modules. 2014-04-21 01:59:43 +01:00
Damien George 3771a097da stmhal: Improve USART class, to be more like SPI and I2C.
The three classes I2C, SPI and USART now have a fairly uniform (Python)
API.  All are constructed, initialised and deinitialised in the same
way.  They can have most of their parameters set, using keyword arguments.
All have send and recv (although slightly different with I2C requiring an
address in master mode).  recv can do inplace receiving (ie store the
data in a previously-created bytearray).

It's just polling mode at the moment, but interrupt and DMA would be
nice to add.

Damien George ff91156d34 stmhal: Improved configurability for I2C and SPI busses.
The HAL handles for the I2C/SPI objects are rather large, so we don't
want to unnecessarily include them.
